> I've never kept any laptop as long as I've kept the M1. My 2015 MBP would like to have a word. It’s the only laptop purchase I’ve made. I still use it to this day, though not as regularly. I will likely get a new MBP one of these days.
My wife still uses my 2012 MBP 15 retina as her daily driver. The battery's terrible but everything else works fine.
The 2012 MBP 15" Retina was probably the only machine I bought where the performance actually got better over the years, as the OS got more optimized for it (the early OS revisions had very slow graphics drivers dealing with the retina display)
The M1 Pro on the other hand, that was a true upgrade. Just a completely different experience to any Apple Intel laptop.
